Main research question
As a paleoichthyologist, I focus my research on the link between Evolution and Environment in deep times, and notably the balance between climate and geology and their impact on faunas.
Topics of study
I address questions in evolution: fossils and their interest to solve phylogeny deep nodes ; evolution of complex structures/ key innovations ; prospects in bone paleohistology. The phylogeny and distribution of both extant and fossil fish allow me to propose a history for ancient hydrographical connections.
I describe the ichthyofaunas yielded by various Tertiary sites from Afro-Arabia and the assemblages allow me to characterise aquatic paleoenvironments.
I cross information on the fossil fish ecology with the chemical signals they recorded (δ180) to catch the water cycle at the scale of the basin. I do the same with sclerochronological tools (growth of hard parts) to evaluate seasonal variation intensity. The latter project implies an experimentation developed in collaboration with Géraldine GARCIA.
